By Mike Spector, Joshua Franklin, Greg Roumeliotis and Anirban Sen.: NEW YORK, Oct 25 (Reuters) - Just a few months ago, WeWork’s co-founder Adam Neumann was being courted by Wall Street’s top investment bankers in anticipation of one of this year’s most high-profile initial public offerings. By October, with the IPO abandoned and his office-space sharing company bleeding cash, Neumann found himself late on a Sunday evening pleading with WeWork’s largest lender for a $5 billion lifeline, people familiar with the matter said. The message was clear - without new financing WeWork would run out of money within weeks.
